 Baldwin, Cattell, Osborn, Hyslop and others, 

 a,nd was closed by Prof. Morgan. 



The Fisheries, Game and Forest Commission 

 of the State of New York, in its annual report, 

 recommends that power be conferred upon the 

 Commissioners to close streams or other bodies 

 of water in the State for a term of years, not to 

 exceed five, when in their judgment it is neces- 

 sary to resort to such procedure to enable fish 

 planted by the commission to obtain suitable 

 size, before fishing of any kind is permitted. 

 It is stated that salmon planted in the Hudson 

 Eiver would do well if it were not for dams and 

 nets. The Commissioners recommend as a 

 public necessity that two bodies of water in the 

 Adirondack region, to be selected by the Com- 

 mission, be set aside by law and used as stock 

 waters to supply eggs of lake trout and other 

 fish for the public waters of the State. They 

 also recommend that forest lands in the Adiron- 

 dack and Catskill region be purchased, until 

 the entire area be included in the forest pre- 

 serve. 



The Proceedings of the Chemical Society 

 (London) issued on January 14th contain an 

 abstract of a paper by Prof. Dewar, on the 

 liquefication of air and research at low tempera- 

 tures. The author reviewed the forms of ap- 

 paratus that had been used in low temperature 

 research, pointing out that the best and most 

 economical plant for the production of liquid 

 air or oxygen was one based on the general 

 plan of the apparatus used by Pictet in his 

 celebrated experiments on the liquefaction of 

 oxygen in the year 1878. He described his 

 own experiments, and stated that Prof. 01- 

 zewsky's claim to priority was fantastic. In 

 the discussion that followed Lord Playfair and 

 Dr. Armstrong deprecated the attacks that had 

 been made on Prof. Dewar. Mr. Blount de- 

 scribed the Linde process for liquefying air. 

 Trials of the process had been made on a con- 

 siderable scale, and there appeared to be no 

 difficulty in liquefying air cheaply and in quan- 

 tity. At the close of the exercises Prof. Dewar 

 said that the late Prof. Wroblewski, as early as 

 the year 1884, predicted that liquid air would 

 be the refrigerating agent of the future ; his 

 prophecy seems about to be realized. 



We learn from Nature that at their scientific 

 meeting on March 3d the Zoological Society of 

 London propose to discuss the much-vexed 

 qiiestion of zoological nomenclature. This sub- 

 ject will be introduced by Mr. Slater, the Secre- 

 tary of the Society, who will read a paper on 

 the ' Rules for naming Animals,' lately adopted 

 by the German Zoological Society, and point 

 out the divergences between them and what is 

 called the Stricklandian Code of Nomenclature, 

 recognized by the British Association, and 

 usually followed in Great Britain. 



The Agricultural Society of Austria has con- 

 cluded arrangements for holding an interna- 

 tional agricultural machinery fair in Vienna, 

 which is to be opened on March 9th, and will 

 last for six days. 



Prof. D. G. Beinton began on February 7th 

 a course of eight lectures on the ' Scientific 

 Study of Man,' to be given on successive Fri- 

 days at the Academy of Natural Sciences. The 

 lectures are as follows : 



1, ' The Universe and Man from the Stand- 

 point of Science; ' 2, ' Man's Position in the 

 Chain of Animal Life; ' 3, ' The Origin of Man; ' 

 4, ' The Races or Varieties of Man; ' 5, ' The 

 Geographic Distribution of Man; ' 6, ' Man as a 

 Wild and as a Domesticated Animal; ' 7, ' The 

 Metaphysical in Man; ' 8, ' The Man of the 

 Present and the Future. ' 



At the annual meeting of the American For- 

 estry Association in Washington the member- 

 ship was reported to be 632, and it was an- 

 nounced that the Association would be incor- 

 porated in the District of Columbia. The es- 

 tablishment of a monthly or bi-monthly publi- 

 cation, as the official organ of the Association, 

 was recommended, and a plan was submitted 

 for the affiliation of State Forestry Associations 

 with the National Association. 



M. Jules Reiset, the eminent chemist and 

 agriculturist, member of the Paris Academy of 

 Sciences, died at Paris on February 5th, aged 

 78 years. 



Resolutions have been adopted by the New 

 Mexico Agricultural Experiment Station to the 

 effect that great injury has already been done 

 to the agricultural and horticultural interests 

 of the Southern States by the introduction of
